In fact my next objective is to start understanding better how the dependencies work to try to make better and more portable builds. Also I would like to try (if possible) to update the versions of the libraries used for the builds in Windows.

Just one comment: I have changed the fix for the Volumetric and did it in a different way because there was still something not correct when rendering a volume on top of a transparent background.

I've been working on the dependencies and libraries to avoid the traditional problems with libjpeg, etc, so I've changed the dependency system in the Exporter. To make this build as "distro-independent" as possible, I've tried to optimize it to match the Blender website Linux 64 glib2.11 build.

Please will you test it to see if it works correctly without libpng, libjpeg, etc, issues?
